8. COMPLIANCE PROVISIONS AND TEST METHODS

8.1 Calculation of VOC Content: For the purpose of determining compliance with the VOC content limits in Table 1, the VOC content of a coating shall be determined as defined in subsection 4.64, 4.65, or 4.66. The VOC content of a tint base shall be determined without colorant that is added after the tint base is manufactured. If the manufacturer does not recommend thinning, the VOC Content must be calculated for the product as supplied. If the manufacturer recommends thinning, the VOC Content must be calculated including the maximum amount of thinning solvent recommended by the manufacturer. If the coating is a multi-component product, the VOC content must be calculated as mixed or catalyzed. If the coating contains silanes, siloxanes, or other ingredients that generate ethanol or other VOCs during the curing process, the VOC content must include the VOCs emitted during curing.

8.2 VOC Content of Coatings: To determine the physical properties of a coating in order to perform the calculations in subsection 4.64 or 4.66, the



reference method for VOC content is U.S. EPA Method 24, incorporated by reference in subsection 8.5.9, except as provided in subsections 8.3 and 8.4. An alternative method to determine the VOC content of coatings is SCAQMD Method 304-91 (Revised 1996), incorporated by reference in subsection 8.5.10. The exempt compounds content shall be determined by SCAQMD Method 303-91 (Revised 1993), BAAQMD Method 43 (Revised 1996), or BAAQMD Method 41 (Revised 1995), as applicable, incorporated by reference in subsections 8.5.8, 8.5.6, and 8.5.7, respectively. To determine the VOC content of a coating, the manufacturer may use U.S. EPA Method 24, or an alternative method as provided in subsection 8.3, formulation data, or any other reasonable means for predicting that the coating has been formulated as intended (e.g., quality assurance checks, record keeping). However, if there are any inconsistencies between the results of a Method 24 test and any other means for determining VOC content, the Method 24 test results will govern, except when an alternative method is approved as specified in subsection 8.3. The District Air Pollution Control Officer (APCO) may require the manufacturer to conduct a Method 24 analysis.

8.3 Alternative Test Methods: Other test methods demonstrated to provide results that are acceptable for purposes of determining compliance with subsection 8.2, after review and approved in writing by the staffs of the District, the ARB, and the U.S. EPA, may also be used.

8.4 Methacrylate Traffic Marking Coatings: Analysis of methacrylate multicomponent coatings used as traffic marking coatings shall be conducted according to a modification of U.S. EPA Method 24 (40 CFR 59, subpart D, Appendix A), incorporated by reference in subsection 8.5.11. This method has not been approved for methacrylate multicomponent coatings used for other purposes than as traffic marking coatings or for other classes of multicomponent coatings.
